HSP70 — Camelina sativa

Summary

CsHSP91 (CSA09G095080, also known as HSP70) on Camelina sativa chromosome 9 encodes an ATP-dependent protein folding chaperone with ATP hydrolase activity, ATP binding, protein binding, and heat shock protein binding functions, and is a member of the Hsp70 family. The gene is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, the ERAD pathway, protein refolding, the MAPK cascade, signal transduction, and responses to stress, heat, salt, and virus. It is linked to pollen tube growth and has been connected to protein folding and oxidative protein folding. The encoded protein localizes to the ER lumen, ER chaperone complex, chloroplast membrane, tonoplast, plastid, and other compartments. Studies of related genes in other species link the family to heat tolerance, virus resistance, stomatal closure, and plant growth.
